Where does this toner go in my routine?

Straight after cleansing, morning and evening, while the face is still damp. Anything thinner than a toner goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Hyaluronic Acid and not three changes at once.

What else is on the list besides Hyaluronic Acid?

Allantoin, Hamamelis Virginiana (Witch Hazel) Extract and Chamaecyparis Obtusa Leaf Extract. The order they are printed in on this toner's panel is the order on the box, so you can see where Hyaluronic Acid sits relative to them. Further down the same panel: Malachite Extract, Hydrolyzed Hyaluronic Acid and Sodium Hyaluronate.

How it works

The Ultra-Low Molecular Hyaluronic Acid Toner (REFILL) is a 200ml toner, used straight after cleansing, morning and evening, while the face is still damp. The humectant it is built around is Hyaluronic Acid, named sixth on its own ingredient list. The same list carries Allantoin, Hamamelis Virginiana (Witch Hazel) Extract and Chamaecyparis Obtusa Leaf Extract, so the humectant is not the only thing on it worth naming. How much of the Hyaluronic Acid stays on the skin, and for how long, is decided by the toner format rather than by the list alone. Isntree sells this Hyaluronic Acid toner in Korea, and this is that version.

Key actives

6Hyaluronic Acidhumectant

Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there. It is the entry this toner is named after, and the list carries it.

All products with Hyaluronic Acid

20Allantoinactive

Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. The panel names it twentieth on this toner's list, beside Hyaluronic Acid.

26Malachite Extractmineral

Malachite is a green copper carbonate mineral. Its extract is used in a formula as a source of trace copper. The panel names it twenty-sixth on this toner's list, beside Hyaluronic Acid.

All products with Malachite Extract

33Hamamelis Virginiana (Witch Hazel) Extractplant extract

Witch hazel extract, the classic astringent plant. Its tannins bind to surface proteins, which is the tightening feel a toner built on it gives. It is named thirty-third on this toner's list, alongside Hyaluronic Acid.

34Chamaecyparis Obtusa Leaf Extractplant extract

Chamaecyparis Obtusa is hinoki cypress. Its leaf extract carries aromatic plant compounds and is used in Korean formulas aimed at oily, congested skin. It is named thirty-fourth on this toner's list, alongside Hyaluronic Acid.

33 of 34 explained

Water solvent: Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
Methylpropanediol humectant: Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
1,2-Hexanediol humectant: 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
Sea Water mineral: Sea Water is filtered and desalinated seawater used in place of plain water. It carries magnesium, calcium and potassium, so it brings the mineral balance of the base closer to skin's own.
Glycerin humectant: Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
Hyaluronic Acid humectant: Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
Hydrolyzed Hyaluronic Acid humectant: Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
Sodium Hyaluronate humectant: Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
Potassium Hyaluronate humectant: Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of skin.
Sodium Acetylated Hyaluronate humectant: Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
Hydroxypropyltrimonium Hyaluronate humectant: Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
Sodium Hyaluronate Crosspolymer humectant: Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.

21 more explained

Dimethylsilanol Hyaluronate humectant: Dimethylsilanol Hyaluronate is hyaluronic acid joined to a silicon-based group. It hydrates and leaves a smoother, silkier finish than hyaluronic acid alone.
Hydrolyzed Calcium Hyaluronate humectant: The calcium salt of hyaluronic acid, already cut into short fragments. Short fragments spread more evenly than the full-length molecule.
Sodium Sulfated Hyaluronate humectant: Hyaluronic acid with sulfate groups added, which lets it hold more water than the plain salt. It is used as a strong humectant.
Sodium Stearoyl Hyaluronate humectant: Hyaluronic acid with a fatty stearoyl chain attached, so it can sit in an oil phase as well as in water. It hydrates and leaves a smoother film.
Sodium Oleoyl Hyaluronate humectant: Hyaluronic acid carrying an oleic acid chain, which makes it oil compatible. It hydrates and gives a softer, more cushioned finish.
Betaine humectant: Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
Allantoin active: Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
Butylene Glycol humectant: Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
Caprylyl Glycol preservative booster: Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
Ethylhexylglycerin preservative booster: Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
Panthenol humectant: Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
Xanthan Gum thickener: Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
Malachite Extract mineral: Malachite is a green copper carbonate mineral. Its extract is used in a formula as a source of trace copper.
Disodium EDTA chelator: EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
Pentylene Glycol humectant: Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
Xylitylglucoside humectant: Xylitylglucoside is a sugar-derived humectant, the third member of the xylitol blend. Together the three hold water in the outer layer for longer than any of them does alone.
Anhydroxylitol humectant: Anhydroxylitol is a xylitol derivative used as a humectant. It is almost always part of the xylitol, anhydroxylitol and xylitylglucoside blend sold as a moisture-retention complex.
Xylitol humectant: Xylitol is a sugar alcohol humectant. It holds water in the outer layer of skin and is often paired with anhydroxylitol and xylitylglucoside as a hydration trio.
Glucose humectant: Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
Hamamelis Virginiana (Witch Hazel) Extract plant extract: Witch hazel extract, the classic astringent plant. Its tannins bind to surface proteins, which is the tightening feel a toner built on it gives.
Chamaecyparis Obtusa Leaf Extract plant extract: Chamaecyparis Obtusa is hinoki cypress. Its leaf extract carries aromatic plant compounds and is used in Korean formulas aimed at oily, congested skin.

How to use

Pat two to three drops onto cleansed skin with clean palms or a cotton pad, working outward across the face, then follow with an essence or serum while skin is still damp.

Worth knowing

Patch test on the inner arm before a first full-face application if skin tends to react easily.
Store away from direct sunlight and high heat to keep the texture and scent stable over time.
Introduce one new active at a time when adding this into an existing routine.
